Large print with flat surface base
Hi there !
I'm a new happy user of the PURSA MK3. I usually print with PURSA PLA some small parts.
I tried to print a larger part today, but the first layer looks so terrible that I stoped the print.
A picture is worth a thousand words :
Tried many times, same result
Printer : PRUSA MK3
SLICER : Simplify 3D
MATERIAL : PRUSA PLA
SETTINGS : default /fast
Any suggestion ?
Tks for supporting .
Y.

To me, this looks more like poor bed adhesion, and something else going on, which I can't think of. Maybe minor under-extrusion?
Looking at the corners your LiveZ looks fine to me. I always run with more "squash" than that, so I doubt the LiveZ is your problem. (I generally love blaming things on that though)
Try cleaning your bed with Isoproply Alcohol, and then clean it with something like Windex.
I'm not really sure what would cause this, other than a possible nozzle jam, or a dirty (non-sicking) bed.
